1. The Gospel of Christ to be preached to all nations (Mic 4:2)
    Mt 28:19-20, Mk 16:15, Lk24:47, Acts 1:8, Jn 6:45, Acts 13:47

In the Old Testament, the prophet Micah prophesied that many Gentiles would come to the temple of God and hear the word of God. (Mic 4:2)

Mic 4:2 And many nations shall come, and say, Come, and let us go up to the mountain of the Lord, and to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for the law shall go forth of Zion, and the word of the Lord from Jerusalem.

This gospel, in which Jesus is the Christ, will be preached to all nations as prophesied in the Old Testament. (John 6:45, Luke 24:47, Acts 13:47)

John 6:45 It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me.

Luke 24:47 And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.

Acts 13:47 For so hath the Lord commanded us, saying, I have set thee to be a light of the Gentiles, that thou shouldest be for salvation unto the ends of the earth.

Therefore, we must preach to all nations that Jesus is the Christ. And so it will be. (Mt 28:19-20, Mark 16:15, Acts 1:8)

Mt 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.

Mark 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.

Acts 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
